V MEANS FOR INSER'IING FILLED ENVELOPES IN GARTONS Application filed January 14, 1932. Serial No 586,584.

The present invention relates to means for inserting a coloring envelope in a carton and more particularly 7 to the insertion of envelopes containing coloring matter in packages of oleomargine.

It is desirable that packages of oleomargarine be sold at retail with the colorlng matter contained in separate closures so that the housewife may color the oleomargarine at home.

There are various ways of selling such coloring matter, such for instance as incap sules.

The present invention concerns itself with the equipment of package of oleomargarlne with an envelope containing the proper coloring matter, which envelope is inserted in the package and is available for use when the package is opened.

An object of the present inventionis to provide means applicable to an oleomargarine packaging machine for inserting envelopes of coloring matter in every package or carton of oleomargarine packaged by such machine.

Another object ofthe invention is to provide the provision of means whereby a plu rality of envelopes of coloring matter may be conveniently maintained adjacent the packaging machine and delivered one by one to the packages as the same are completed 111 the packaging machine to the end that every package or carton may be supplied'with an envelope of coloring matter.

A further object of the invention resides in the provision of means for so timing the closing of the package and the delivery of the envelope containing the coloring matter as not to impede the output of the packaging machine.

The above, other and further objects of the invention will be apparent from the follow- I withdrawn one by one and delivered by gravity into an oleomargarine package.

An exemplification of'the mechanism emhodying principles of the present invention is illustrated in the accompanying drawings, and the views thereof are as follows:

Figure 1 is a fragmental top plan view of an oleomargarine packaging machine showing applied theretothe mechanism for supplying envelopes of coloring matter to the packages, which mechanism embodies principles of the present invention.

The drawings will now be explained.

Only so much of the packagingmachine is illustrated, as is thought necessary for complete understanding of the present invention.

Figure 1 illustrates a fragmental portion of a packaging machine suitable for packaging bricks of oleomargarine or similar sub 55 '11 of the blank.

stances and illustrates a row of bricks 1 of oleomargarine which are advanced along atrackway 2 by suitable means. A pile of wrappers for the bricks is supported on a 5 table which wrappers are fed one by one underthe individual blocks 1 as the same are delivered to the table. There is an opening in the table underneath the plunger 5 over which opening the operator places one of the wrappers as the endinost brick 1 is by proper mechanism. 7

A carton blank represented generally at A is fed onto a shelf or table 7 in open position. A substantially circular hook' member 7 8 is carried on a plunger 9, which'is reciprocated by. any suitable mechanism as a part of the packaging machine. The hook 8 is advancedwhere it engages the outermost panel 10 of the blank A and then as the plunger is moved to the left as viewed in Figures 1 and 2, the blank is rolled into boxlikeform as shown in Figure 2, leaving'the endmost panel 11 and its end tabs'flat. The blank A is made with five panels so that when the blank has been. rolled into substantially box-like form as'viewed in' Figure 2, the fifth panel 11 will remain flat for the reception ofthe coloring matter envelope as later described;

The coloring matter inserting mechanism embodying principles of thepresent invention includes a box-12 which is disposed above the shelf or table 7 The box 12 is provided with a follower '13 acting against a supply of filled coloring matter envelopes 14 to urge these envelopes towards the delivery end of the box, which, in the drawings, is illustrated at the right.

Guide means for receiving an envelope from the box 12 are provided at the dis- 5) charge end ofthe box and in the present instance,'such guide means comprise a box-like member 15 fastened against the discharge end'of the box 12 and with a depending chute portion 16 leading downwardly and stopping 'short of the shelf or table 7. The box 12 and the guide means 15 are so positioned with respect to the shelf 7 and the carton blanks thereon as to discharge a coloring matter envelope'14 onto the end tab 43'of the panel The chute 16 is reduced toward its lower end so as to discharge the envelope vertically, while the guide means is enlarged at its upper end to more readily receive an envelope withdrawn from the 69 box 12.

a Means are provided inthe guide means for stopping passage of an envelope along the same in order to insure proper and timed delivery of an envelope onto the blank A ready for enfolding Within the blank when the same is closed by the final operation of the packaging machine. 7

Such means are hereinillustrated as comprising a stop member 17 which is reciprocably projected through the lower part of the chute 16. The stop member 17 is carried on the end of a reciprocable rod 18 mounted in suitablebearings 19 and. 20 in the frame structure, that is, in the uprights for carrying the box 2. A collar 21 is secured to the rod 18 by a set screw 22for limiting movement of the rod for stopping passage through the chute 13, that is, for movement to the rightas viewed in the drawings.

Another collar 23 is secured to the rod 18 near the bearing 20 and between the collar 23 and thebearing 20 a spring 24 surrounds the rod, the tendency of which is to move the rod to stopping position, that is, to the right as viewed the drawings. 7 V

A bracket 25 is suitably secured to the rod 18, which bracket has pivoted thereto at 26 a dog 27 which is normally retained in operative position by a spring 28.

The plunger 9 is provided with a bracket 29 which iarries a finger 3O pivoted in the bracket at 31 and maintained in operative po-' sition by the action of a spring 32 acting against the finger 30 which normally maintains the finger against the stop pin 33. The spring 32 is of sufficient strength so that when the finger 30 engages the dog 27 on the rod 18 movement ofthe rod 18 to the left against the action of the spring 24 may take place for a limited amount of movement. When the rod 18 hasbeen moved to the left by movement of the'plunger 9 to the left a sufficient distance,

the compression of the spring 24 overcomes the springs of the spring 32, whereupon the finger 30 moves away from the dog 27 thus freeing the dog from engagement by the finger whereupon the rod 18 is moved to the right with snap action by the spring 24, that is, the stop member 17 is returned to stopping position.

The illustrated means for withdrawing an envelope 14 from the box 12 consists of suction means and includes a suction nozzle 34 attached to the end of a suction pipe 35 carried on a reciprocating pipe 36, which'pipe in turn is given reciprocable movement by mechanism to be later explained.

I A chamber 37 is connected by means of pipe 38 to a suitable source of suction. The chamber 37 has an outlet 39 opening into the path of movement of the movable pipe 36.

The pipe 36 has an opening 40 for purposes to be later explained.

The pipe 36 and the attendance suction noz- V zle 34 is given reciprocable movement by means of a rod 41, mounted in brackets 42 attached to the side of the box 12, by a lever-43 which is connected to part of the packaging machine mechanism having reciprocable movement, such. as illustrated in Figure 1.

The lever 43 is provided with spaced ears 44 while the rod 41 is provided with a roller 45 disposed between the ears 44 so that as the lever 43 is given reciprocable action through the instrumentality of the packaging machine the cars 44 will selectively contact the roller 45 and impart reciprocal movement to the rod 41 and the attached suction nozzle 34. The ears 44 are spaced a greater distance than the diameter of the roller 45 to provide lost motion for these parts. The lost motion connection just mentioned allows the nozzle 34 to dwell at each end of its stroke, so that proper suction connection may be made with the endmost envelope 14 in the box 2 when the nozzle is moved inwardly and a sufficient length of time may ensue after the nozzle drops the envelope into the chute 16 before return movement of the nozzle commences.

The stop 17 is actuated by the packaging machine mechanism in timed relation so that the stop will be moved from stopping position to allow an envelope to drop into the carton in the position illustrated in Figure 2 just prior to the time the carton is lowered for final closing.

After an envelope has been delivered onto the tab 43 of the panel 11 of the blank the packaging machine then lowers the blank to dotted line position of Figure 2, during which time the plunger 44 becomes effective to move the panel 11 against the adjacent side of the box and other mechanism, not shown, moves the tab 43 against the end of the box and tucks in the flap thereof so as to lock the package in closed position During the time the blank is rolled into the position shown in full lines in Figure 2. and the time it is lowered as just described, the opposite end has been closed by suitable mechanism and the near end has been closed all except as to the flap 43 on the panel 11 so that the envelope of coloring matter is inserted or delivered to the box immediately prior to final closing of the same. that is, immediately prior to the closing of the final end flap. After the carton has been closed in the manner described, it is moved by suitable mechanism to a convenient plax e for storage or for packing in cases or crates.

The operation of the mechanism of the present invention is as follows:

The full line positions shown in Figures 1 and 2 are the positions assumed by the parts after an envelope 14 has been withdrawn from the box 12 and delivered to the chute and passed the stop 17. The envelope is in dicated at 14 in Figure 2 with an edge lying against the end tab 43 of the panel 11.

As the carton descends for the final closure, the plunger 9 moves to the right to engage another blank to roll it into the posititin of Figure 2. n the return movement of the mechanism, the rod 41 is moved by the lever 43 so that the suction cup or nozzle is brought against the endmost envelope 14 in the box 12', which movement brings the port 40 in the pipe 36 in register with the port 39 in'the chamber 37 so that the cup is placed in communication with the source of vacuum Whereupon the endmost envelope ispicked up by suction in the suction cup 24. I As the-parts continue the cup then moves to the right until the port 40 is in communication with the air whereupon the suction in the cup is broken and the envelope 14 falls downwardly by gravity through the guiding means 15 against the stop '17. In the meantime, movement to the left of the plunger 9 will bring the finger against the dog '27and move. the stop/17 out of stopping position so that the envelope may fall in the position shown in Figure 2,

that is, the position against the tab 43 of the panel 11, whereupon said envelope will be closed Within the package or carton by the closing of the end tab 4 The utilization of anvenvelope for oleomargarine coloring matter is advantageous in that but little space is required for such envelope when filled with the coloring matter. Figure 7 illustrates an envelope 14 enclosed in the package of oleomargarine and as indicated at 14 in Figure 5.

The invention has been described herein more or less precisely as to details, yetit is to be understood that the invention is not to be limited thereby, as changes may be made in the arrangement and proportion of parts and equivalents may be substituted without departing from the spirit and scope of the invention.
